Weird issue. All users RDP into the terminal server to use the ERP system. A handful like RDP to use both screens. Just today when you move a window to the secondary screen, it tears and doesn't load itself graphically. I've always wondered if there's a term to describe that? Anyway, if the user keeps their windows and apps on the primary screen, they work fine.

I'm struggling at finding info on this in teh Googles. I'm also struggling at finding an accurate search term. Has any seen something like this before? Unfortunately, I can't reboot the server until tonight. Might be able to make an emergency reboot out of it over the lunch period, but yeah.

In the attached picture, notice the white lines on the left secondary screen. I maximized that excel file to fill the screen and the white lines are the scroll sliders. The weird part is you can actually still click on things and edit them and they're there, but it doesn't display. Also the second screenshot is a snipping tool shot. It actually grabbed the black lines it's really displaying. The first screenshot is a ctrl+prtscrn.

It is caused by either KB4034664 or KB40341679.

I am an admin for a 200+ Windows Server 2008 R2 RDS farm. All my clients that use MS Office 2013 or 2016 started to notice this today. Through a series of rolling back August updates I have narrowed it down to those two KB's. installed Individually, or in tandem, I can reproduce the anomaly exactly as described.

Just found out most of these users had Windows updates applied yesterday or this morning. Updates specifically for MS applications. A regular windows explorer window can be maximized on the second screen in RDP with no issues. It's specifically MS apps. I'm going to check out the updates and see if there's a deal...

Hmm. Well a little more info - This terminal server is 2008 R2 and virtual through vmware (vcenter 5.5). In the properties for the vmware vga display adapter, the "change settings" on the troubleshooting tab is grayed out. So, I was thinking it might be a vmware setting? Under the hardware settings of the server, I didn't see anything relating to hardware acc under the video card, just the MB allocation amount.

Oh no worries man. I'll have to play around with the settings. Everything is already turned off. And what I mean by everything, is that in the advanced performance settings it's set to "adjust for best performance" which turns all that stuff off.

@Stratos - Thanks for the info! I updated that on the affected TS and I'm going to try and get a reboot in midday...Otherwise I'll have to wait until tonight. My next thought was going to be just reinstall the whole Office suite on the TS.

Good idea johnsnow, I'll try changing the color scheme for some of the users and see what works. If the 24-bit can work, then that might be good enough!
